Can't I do this with a filter?

Hi all

I am doing this

  .choice()
          .when().method(RedisService.class,
"isLsaHtmlDuplicateBody").to("mock:nowhere")
         
.otherwise().to("activemq:getAndStoreHTMLPage?concurrentConsumers=30&asyncConsumer=true");

I tried using a filter first, but I seemed to still be getting data.  Am I
incorrect about the filter?

Thanks

Chris

Thanks Claus

For some reason is was getting a npe with the solution of using the 'not',
so I inverted the method and it works like a charm!

Hi

If you use a filter then you most likely need to invert the method.
eg a isNotXXX method

filter().method(RedisService.class, "isNotLsaHtmlDuplicateBody")
    .to("activemq:getAndStoreHTMLPage")
.end()

And you can use end to mark the end of the filter.

There is also a not predicate in Camel but the DSL is a bit
cumbersome, so I have improved that on Camel 2.10, so you can do

// requires Camel 2.10
filter(not(bean(RedisService.class, "isLsaHtmlDuplicateBody")))
    .to("activemq:getAndStoreHTMLPage")
.end()

For Camel 2.9 or older, you can do something alike

filter(not(toPredicate(bean(RedisService.class, "isLsaHtmlDuplicateBody"))))
    .to("activemq:getAndStoreHTMLPage")
.end()

And then do a static import of the toPredicate method.
